DIVIDER BOARD IFOR IMIO'WQERS.k

Application `filed December'l, 19,27. Serial No. 2` 37 .()64.

'lhis invention lrelates l#to divider `boards for Vmowers .and nioreparticularly to a di- ,vider iboard vpivotally `inounted, so that inyevent of its engagement rwith an obstruction during backing off-thelinower` it,rnay yield inwardly and thus prevent breakage thereof.

Aniinportant object ofthe invention isto provide ina construction'ofit`this character aspringreturn hinged :leaf upon whichthe ydividerboard:is mounted and which is, in atuign, mounted upon the o-utershoe of thereaper, the returninechanism for the leatheprovide ,a^. construction.sue-h Athat when fthe l,ing Qtsucli cliaracterthat it,niaybe entirelyconcealed within t-he structnreof the divider board under tnorina'loperating conditions Aand accordingly imay notloe damaged or interferedwith in its operationrby Contact with materials through which the boardEis Inoving.

A further lobject of the invention is lto i board-isdiexedor moved aboutits pivotethe lspringconnection fonreturning the boardto its i'iornialposition ,is .shifted in such a l,inanner that vit'is wellispaced :fromthe pivotal mounting of the ,board and accordingly `the spring A,rnayexercise its tension tothe Ybest advantage. v

In this operation, the head 17 is swung outwardly from theplate 12, forcing before it the spring supporting plate 20, with theresult that the rear end of the spring supporting plate moves transversely and the head 28 is further spaced from the pivot 15 than it isnormally. By this movement, the tension of the spring 30 is increasedand the angular pull thereof likewise increased, with the result thatthis spring will immediately, upon release of the pressure holding theboard in its abnormal position, move the boardback to its normalposition in alignment with the plate 12. In doing this, the spring 21,which is a relatively heavy spring, also acts to assist. in the reVturn, ofy the board, for the tension of this spring being applied tothe plate 21 rearwardly of the pivot. thereof, applies pressure t-o thehead 17, tending to rotate the late 13 andy accordingly the board towhich itis attached. In the normal position of the parts, the head 17vand plate 2O together with the spring 30 and the connect-ions betweenthe plate 20 and the spring are concealed within the slot of the boardand accordingly held from access to materials being cut by the mower.

As the construction hereinbefore set forth is capable of a certain rangeof change and modification without materially departing from the spiritof the invention, I do not limit myself to such specific structureexcept as hereinafter claimed.
